username and email address are not synomonous for login

I fail to be able to push to my repository with the error:

— Error During Push

---Mercurial reported error number 255:

---abort: http authorization required

I am pushing to https://riclf@bitbucket.org/riclf/inemergency

I have also tried https://riclf:password@bitbucket.org/riclf/inemergency

So I go to the bitbucket.org site and try to log into my account, using my Username (riclf) and Password, both of which are correct. The login fails with multiple tries. So I use my email address (ric@innermagic.com) and the same Password and I get in,

Now, when I look at my account, I can verify that my Username IS riclf (Welcome riclf). So what's up ?

I cannot use my email address in my push command and my Username is non-functional for purposes of logging in !

The result is that I am not able to Push my project to my repository.

Thanks.
